1.Use a flexible measuring tape or length of string. Wrap it around the finger you'll wear your ring on - if you're creating a ring stack, consider where on your finger the ring will sit. If using string, mark the point on the string where the ends meet with a pen.

2.Lay the string on a flat surface and use a ruler to measure the length (in inches or millimeters) up to the mark. Compare your measurement to the size chart above to determine your ring size. If you are between sizes, opt for the larger size.

A Smart Ring for Sleep, Built for Overnight Comfort

CUDIS 002 Classic is designed for people who want a smart ring for sleep without the bulk, screen distraction, or constant adjustment that can make other wearables harder to keep on overnight. Its lightweight design and sleep-first positioning make it a better fit for users who care most about comfort, recovery awareness, and long-term consistency.

For sleep-focused users, comfort matters just as much as data. A ring that feels easy to wear at night is more likely to stay part of a real routine, which is why the Classic model leans into a lighter, more minimal form factor instead of a louder performance-first look.

If you are comparing CUDIS options and want a more active-use product, you can compare this page with the CUDIS 002 Sporty Ring.

Why a Titanium Smart Ring Feels Easier to Wear Every Day

CUDIS 002 Classic is positioned as a titanium smart ring for users who care about durability, light weight, and a more refined daily-wear experience. Titanium helps support a premium feel while keeping the ring light enough for all-day and overnight use.

That combination is especially useful for users who do not want their wearable to feel intrusive. Instead of competing for attention, the Classic model is designed to stay subtle, comfortable, and easy to integrate into work, rest, and everyday routines.

For users who want more background on the platform logic behind the product, they can learn more about how CUDIS works.

What This Sleep Tracker Ring Helps You Monitor

CUDIS 002 Classic works best as a sleep tracker ring for people who want a clearer view of their rest and recovery patterns over time. Depending on the live product experience and available features, it may help users follow trends related to:

sleep
recovery
stress
daily wellness rhythms
habit consistency

Rather than treating health data as a single number, the ring is better understood as a tool for awareness. That makes it easier for users to connect their nights, their recovery, and their next-day routine in a more practical way.

A Sleep Ring for Daily Life, Not Just Bedtime

A lot of people searching for a sleep ring are not only trying to improve their nights. They also want something they can keep wearing during the day without feeling like they are carrying around a sports device. That is where CUDIS 002 Classic can make sense.

Its more understated design helps it fit office settings, home routines, travel, and low-friction everyday wear. In that sense, it is not just a smart ring sleep tracker — it is also a more lifestyle-friendly wearable for people who want sleep and recovery insights in a calmer, more minimal format.

If your priority is a stronger workout and training angle, the Sporty model is the better comparison point.

Classic vs. Sporty: Which CUDIS Ring Fits You Better?

Choose CUDIS 002 Classic if your top priorities are sleep comfort, lightweight wear, understated design, and a ring that feels easier to leave on overnight. It is the better fit for users who want a quieter, more refined daily-wear experience.

Choose Sporty if you want a stronger training-first identity, a more active-use exterior, and broader workout-oriented positioning. If that sounds closer to your use case, compare this page with the fitness ring without subscription option in the lineup.
